ROOF MATERIALS FOR YOUR LOG HOME
Your roof is a great opportunity to make a dramatic statement to
the world. This colorful creation is going to sit atop a unique,
custom home, and no matter what material you choose it's going
to look awesome. There are more choices on the market today than
ever before, and an extra investment will probably make a bigger
impact here than elsewhere in your home. Even asphalt shingles
have taken on a new personality. Here are some varieties modern
technology has made available to us (my cost estimates are very
broad, and only meant for comparison's sake).
ASPHALT (or Composition) SHINGLES: (also known as three-tab
shingles) The most commonly used shingles, these are made from a
mixture of asphalt and fiberglass. The ceramic granules protect
the asphalt from the sun's UV rays. We tend to buy them
according to life expectancy, which starts at 15 years for the
thinnest shingles, 25-30 years for the next level. Their
lifetime depends on the environment and how well the roof is
vented. This roof will cost around $50-$150 per 100 square feet.
LAMINATED FIBERGLASS SHINGLES: Also called architectural or
dimensional shingles, this shingle is still made from a mixture
of asphalt and fiberglass, but is built much thicker, giving it
a more three-dimensional look. Architectural shingles make the
roof look more textured, are larger than a standard shingle, and
come in an amazing variety of shapes. They are usually
guaranteed for 40 years and could easily cost twice as much as
standard asphalt shingles.
METAL ROOF: Metal is one of the more sought-after roofing
materials for log homes. Usually made of steel, aluminum or
copper, the most commonly discussed metal roof is the standing
seam - sometimes called vertical panel - roof. You can also get
metal shingles that resemble cedar shakes, slate, or tile. There
are several advantages to using a metal roof, not the least of
which is its fire resistance. These roofs are also remarkably
lightweight, and stand up to hurricane-force winds. This roof
will generally cost about $100-$600 per 100 square feet (very
big range of materials and composition). Life expectancy is
anywhere from 30-50 years up to 100 years.
CEDAR SHAKES and SHINGLES: The difference between a Cedar Shake
and a Shingle is that, generally, the shingle is sawn on both
sides and the shake is hand-split on one (or both) sides. The
shake tends to be thicker. Cedar looks picture-perfect when
installed, and will age to a beautiful gray, given the right
environmental conditions. However, it is prone to moss and
mildew, and the shingles have been known to curl. To combat
their inherent vulnerabilities, many brands are treated to
prevent mildew, and others are treated for fire retardancy. The
average life expectancy is about 25-30 years and could cost
$400-500 per 100 square feet.
CONCRETE TILES: You'll find a lot of concrete roofs in Europe.
Needless to say, they are incredibly durable and fire-resistant,
and because concrete takes stain so well, you can find it in up
to 50 colors. Of course, this is a hefty solution for a hefty
home: figure out about 1000 pounds per 100 square feet. Concrete
roof tiles come in several profiles, and have a life expectancy
of about 80 years and can cost around $200-400 per 100 square
feet. There will be extra expense for beefing up the rafter
system to support the weight.
CLAY TILES: When you mention clay tiles, most of us think of the
half-round shapes on Spanish Mission buildings. Think no more!
Clay tiles are flat, interlocking, rectangular, slabs... and of
course barrel-shaped. You can get them in solid colors or
blends, textured or smooth. Figure about 1000 pounds per 100
square feet. They have a life expectancy of about 50 years, and
can cost $400-$500 per 100 square feet.
SLATE: Complex, durable, and beautiful, slate has a life
expectancy of 60 -125 years, and more. Your standard slate is
about 1/4" thick. The slates are overlapped so that the bottom
edge of the slate is actually covering two additional layers,
and less than half of the slate is exposed. This standard
thickness will weigh about 750 pounds per 100 square feet.
Modern variations of slate roofs are: Rubber Slate
(post-industrial waste) and Engineered Slate (marble dust and
polyester resins). A real slate roof can cost up to $1000 per
100 square feet installed.
One of the things I've noticed over the years is that lighter
colored asphalt shingles have a tendency to streak as rainwater
washes down the roof. Even my dark green roof is streaking in
one spot, although the green masks the darker stain. Before you
decide on a color, do yourself a favor and drive around the
neighborhood; look for other houses with similar shades. Then
you can make a decision as to what's more important: how your
roof will reflect or absorb the heat, or which one looks better
over the years.
